Conveyors on food and beverage lines must stand frequent wash-down, cope with temperature and be safe in food contact. A modular plastic belt is built from plastic modules: open areas drain and cool, damaged modules are replaced individually, and the belt can turn. A flat-top slat chain conveyor uses plastic or stainless chain and carries bottles, cans and cartons in single file and accumulates them; it is the workhorse of filling and packing lines. Belt and chain materials are chosen by product, temperature and cleaning chemicals, and food-contact grades come with the compliance documents for the selected grade.
| Modular belt pitch | Commonly 25.4 mm and 50.8 mm |
|---|---|
| Belt material and temperature | POM about −40 to 100 °C; PP about 0 to 90 °C |
| Chain width | Commonly 82.5 mm and 114.3 mm |
| Stainless chain curve radius | Minimum about 200–500 mm, by chain type |
| Food contact | Food-contact documents per selected material (e.g. EU 10/2011); for POM copolymer, US FDA 21 CFR 177.2470 |
